To all whom t mag/-concerw Be itknown that I, Runonrn HOFFMAN, e' citizen or" the United States, Yresiding etV Kankakemin the countyof 'Kankakee Y and Stateofllinois, have invented e Yeert-:iin new and useful Oil Stove, or" whichthe"followingV isaspeciiicetion, Y Y rl`he invention jrelatesYA-to oil stoves-for type each coinprisinirnburner'bowl connected with e suitable Ysource of oil supply in n true vertical yexpenditure of eortLf and controlled by means-adapted to vary .the relative heights of 'theA oil level andthe attemptshavebeen mede to Vovercome this difficulty among which wes'the use fof a exibleconnection between the Supply pipe `Such Vconnections Y j-under the andv fthejburner bovvll Weremade from .pipe ofsubstantial length and then theiriexibility was obtained by the insertion in the pipe of n leprofe,IJ-'shapedV part .or diaphragm. This proved impracti-v cal beca-use the endof the pipe connected to :the burner travelledV in? the arc Voi e circle. is a result,`it Wes impossible With'this construction to maintainVV the burner bowl in a 'true horizontal position and hence to obtain Vin the loperrationof the burner e uniforin and ethcient flame. Y A priinnry Vobiect of my invention-1s to overcome the cliiiculties Vabove referred tov by the provision-.of a Ineens for conducting the oil from a ixedrsolurce of supply to the `burner bowl, which is, first, absolutelyeoilvtight und,'second,1 which is capable ofper-'g lnittin'g the burnel'fto, be raised and lowered pat-ligand with a minimum clin attaining this objecufl employ vin myv preferred construction e. seamlessinetallic tube' Whichris renderedreadily fiexible by spinning' e. helicalv cry. and collapsingP the tube endwise so asilo bring the walls of thefgroove almost uniformly "throughout the entire: length V*of objection, Vjzind this 'is' ing the oil-co`nduct1ng @uniform rate to" the burner.

Frein the lower end of the stein 9 anexible conductor ljleads in a with generally horizontal direction to an oil supply pipe 14C. The latter extends blongitudinally ot the stoveV andv is connected by means of a. pipe l5 with the supply tank or reservoirk 17. constitutes an oil receptacle well 16 ot an oil Vrlhis well also Yin which the level ot the oil is maintained constant in a well known inanner by the reservoir 17.,

land it willbc observed that by eiiectig a relative vertical rnoveinent between the re-v 16, the height of the fiaine niay be varied at will. 'In the present instance, the receptacle Y8 isiraised and lowered by ineans' oi the device l2' withreterenceto a constant oil level indicated in Fig. l.

be oi any well known or rpreferred* construction', comprising the burner bowl 8 adapted to receive an annular lighting ring (not shown) and to. support a chimney 18." j Y Thev stein 9 which depends troni the trough 8 is rigidly secured tothe trough at the lower edge thereof as by brazing, so as to .provide a vcoininunicationy betweenY the trough andthe source of oil supply. The stein isfinade of substantial lengthand at its lower end enters a fitting 19 arranged 'for vertical inovenient within the support lO.

The support 10 comprisesV abraclretQO ot inverted U-'shape havinga trontwall 2l and provided with flanges 22 by nieans of .which the bracket is rigidly Vsupported upon'a vlongitudinal portion of the stove `tranne A.

Rigid with the top portion of the bracket is the nieniber or sleeve l1 which is vertically V.disposed and adaptedY to neatlyl receive Vthe stein 9 so as toi guide the latter in Vits rvertical movements. f f

For the purpose of enabling the raising and lowering device 1Q, tov coact with the sleeve l1 and thestern V9. the sleeve is eX- ternally threaded as at 23V andthe stem is provided withaV fixed .collar 24. Said device 12 has an internally threaded nieniber with a support l() einthe receptacle or well `rality f these guide Y or nut 25 engaging withV the screw' threads 23 and having a pair ot upstanding arins'Q shaped at their upper ends to engage with the inernber E24 which atits upper peripheral edge is provided'with an annular rim or flange 27. The upper ends of the ari'ns '26 are bent to torni fingers i8 adapted to Y -slidably eiigage'with said flange E27 and at the rotation ol' the ineinber or nut 25 the Y aising or lowering oi *the burner is ettected.

The flexible pipe connection'l extends directly between the lower end of the steni;

9 and the feed horizontal direction. Y

it coinprises a norn'ially straight seamless.,

pipe '14 in a substantially S5` ln its preferredv torni i'netallic tube of relatively short length consisting oit a plurality oii'relatively inovable but non-slidable sections 32 together siinulating` beilows-diaphraginsx These are formed by spinning a helical groove ot substantial depth ina plain tuberot suitable material, such as tively'lightgange, and then collapsing the .tube eiidwise sores to bring the walls ot the groove almostk together as shown in 5f. The result, it will be apparent,y is the/formation of a conductor having va pliiot helically shaped together but capable .of Vrelative movement to perinit the bending or flexing of thecondutor, and in such a way Vasfto permitthe burnerbowl to'be raised and lowered inaA maintained at true' verticalpath and hence Y p Thus, `1t

The feed pipe la is stationarily mounted" in any suitable manner in the stoverame A and carries upon its upper'sidethe fittings 33 :trom which the flexible connections 13 lead to the several burners of the stove. Each of said fittings is secured'upon the pipe 14 in any suitable or preferred waylas by means of a clamp 37 encircling the-pipe and having a screw 58Y engaging the fitting',YV

For the purpose-of indicating the various A operative and inoperative `positions. oi"v the burner, I provide'an indicator comprising a pointerl carried theL iitting 19 (Figs. 1 and 2) and a scale formed on the front AWall 22 of the bracket'ZO. The pointer A5l is i mounted uponra boss 52 onftlielittiiig, as 'by means of a screwf`53, a slot'lbeing prof vided'in the Vwall 21 of the bracket to receive lthe boss. The scale upon the wall Qlmay"V consist of suitable legends vsuch as Out, Med, High and Light, stamped upon the Vforward face of the wall 2l. i

ot dust and 'dirt which might interfere with the tree iiexing of the' pipes. Herein VVthis means is in the torni of a sheet metal plate -55 suitably secured in position over the',V diaphragins `13.
